The characteristics of discharge parameters of refine rp graphite electrode factory

⑴ Peak current (IP) characteristics: The larger the peak current, the smaller the loss of the refined rp graphite electrode factory and the larger the surface roughness; under certain area conditions, the processing speed is also faster. When the peak current > 12 A, the loss of the refined rp graphite electrode factory reaches the minimum; when the peak current > 32 A, the machining starts to become unstable.

Selection criteria:

Select according to current density:

Current Density – The current value specified in the unit area of the refined rp graphite electrode factory is called the current density of the refined rp graphite electrode factory. The experiment results: Copper refine rp graphite electrode factory: 6-8 A/cm2 refine rp graphite electrode factory: 5-7 A/cm2⑵ Pulse width (ON) definition: Pulse width is added to the refine rp graphite electrode factory and discharge on the workpiece The duration of the voltage pulse across the gap.

Features:

The larger the pulse width, the smaller the loss of the refined rp graphite electrode factory and the larger the surface roughness; under certain current conditions, the processing speed is also faster.

When the peak current is less than 12 A, the processing speed increases with the increase of the pulse width. When the peak current is more than 16 A, the processing speed decreases with the increase of the pulse width. Experiments show that: when the pulse width is more than 150 μs, refine rp graphite electrode The factory’s loss value can be reduced to less than 1% to achieve low-loss processing goals, but it cannot exceed 420 μs.
